Abstract: In the multi-layer inductor, all of the plurality of through conductors are not aligned in a straight line, and the distance between the through conductors can be sufficiently kept in the element body having a predetermined dimensional standard. Therefore, the through conductor as a heat source is apart from each other, and the heat of the through conductor can be efficiently radiated to the outside of the element body.

Abstract: A laminated coil component includes: an element body having a first surface and a second surface facing each other in a first direction; a coil unit formed by laminating a plurality of coil conductors in a second direction orthogonal to the first direction inside the element body; a first lead-out conductor; and a second lead-out conductor. A first coil conductor adjacent to the first lead-out conductor in the second direction includes a first side portion extending along the first surface, on a first surface side. A second coil conductor adjacent to the second lead-out conductor in the second direction includes a second side portion extending along the second surface, on a second surface side. The first side portion has a larger line width than other side portions of the first coil conductor and the second side portion.

Abstract: In the multi-layer inductor, the internal electrode includes the auxiliary conductor, and the auxiliary conductor is jointed to the external electrode at the end face. Therefore, when a defect occurs in a part of the through conductors, a current flows through the remaining through conductor(s) and a current also flows through the auxiliary conductor. Therefore, overheating at the joint surface between the remaining through conductor(s) and the external electrode can be prevented, and cutting and/or fusion starting from the joint surface can be prevented.

Abstract: A multilayer LC filter array includes an element body of a rectangular parallelepiped shape, a first filter including a first inductor and a first capacitor that are disposed in the element body, a second filter including a second inductor and a second capacitor that are disposed in the element body, a first input terminal electrode and a first output terminal electrode that are connected to the first inductor, a second input terminal electrode and a second output terminal electrode that are connected to the second inductor, and a ground terminal electrode that is connected to the first capacitor and the second capacitor. The element body includes first and second principal surfaces opposing each other. The ground terminal electrode is disposed at a center of the first principal surface. The first input terminal electrode, the first output terminal electrode, the second input terminal electrode, and the second output terminal electrode are disposed at respective different corner portions of the element body when viewed from a direction orthogonal to the first principal surface.
